I applaud anyone who does it for the nostalgia.
About a year ago we gave up on physically owning music. We had moved a 550 CD collection to our new E TN home.
And that’s not nearly all of them.
It had literally been years since we had drug one out to listen to, and we decided to let them all go. We have a huge McKays Used Books and CD’s near us that bought them in batches for what added up to maybe $400 altogether. Though a pitiful fraction of what they collectively cost, they’re gone now and we haven’t missed them at all. Apple Music puts 99% of what we might listen to at our fingertips, though there are of course many options there.
As far as sound quality/fidelity, I don’t think there’s a whole lot of difference between formats to our aging ears.
